Well, maybe this diagram will help you, i know how to do it but can't really put it to words because i don't know half of the part names! Hope this helps give a better idea of what is where on the carb to give you a better idea of what you have to do. Its a briggs diagram but should help! Good Luck. (also, the text below goes with the pic, here is the website anyway!!: http://www.lawn-mower-shop.com/carb2.htm )

The pic may be easier to read on the website!! Good luck!

LawnBoy Duraforce is their own engine, 2 cycle - been used for the past few years. I have one on a commercial 21" machine, not the silver series like yours. I don't know the differences, but one thing that may be a problem is a clogged screen in the carb bowl.

The exploded picture above was not of a LB, but a B&S (I think that what was said). The LB isn't that much different, but one major difference is a screen over the pickup that is deep inside the bowl, below the float. I had mine clogged earlier this summer, and the pattern was similar to what was stated, until finally it would not start.

Do you have a parts manual? If not, go to the LB website and find the right parts manual, get an exploded view of the carb. You will probably find the screen I am speaking about. It is part #9 in the drawing.

I may not have the right s/n series for your model (10323), but you can back up and find the right s/n drawing. I doubt the carb has changes.

Just something for you to try to resolve the problem -- maybe my idea is right, maybe not.
